rman report schema in 12c

The "report schema" command has been around a long time in rman but has been enhanced (slightly) to support pdb/cdb. It's quite a useful utility for just listing datafiles/tempfiles without having to write any sql.

The summary it gives for pdb/cdb is also very handy (perhaps more useful than it was for a 'normal' database)

List of Temporary Files
=======================
File Size(MB) Tablespace Maxsize(MB) Tempfile Name
---- -------- -------------------- ----------- --------------------
1 155 TEMP 32767 /oracle/ED12G/oradata/orcl/temp01.dbf
2 87 PDB$SEED:TEMP 32767 /oracle/ED12G/oradata/orcl/pdbseed/pdbseed_temp01.dbf

4 20 TEST:TEMP 32767 /oracle/ED12G/oradata/orcl/test/temp01.dbf

We can easily see which files belong to which PDB as they are displayed in PDB:TABLESPACE format.
